How to only list affilations for some of authors, but not all?

[misilot]

Hello!

I have 6 authors, and only 3 of them have affiliations we want to to call out. Is there a way to not have an affiliation for the users?

For example

\authorsnames{A Smith, B Smith, C Smith, D Smith, E Smith, and F Smith} \authorsaffiliations{{Committee Member}, {Chair}}

I want B Smith and D Smith to have the Committee Member affiliation, and F Smith to have the Chair affiliation.

Thanks!
